Abstract

In this study all-poly(ethylene terephthalate) composites were developed and their (fracture)mechanical properties were investigated. Glycol modified poly(ethylene terephthalate) (PETG) and high tenacity PET multifilament were used as matrix material and reinforcement, respectively. The reinforcement was aligned in unidirectional (UD) and crossply (CP) manner and its content varied between 30.70 wt%. The composite plates were prepared via winding the reinforcing filament onto alumina plates and matrix film were placed in-betweens. This pre-product was consolidated by compression molding. The tensile mechanical properties and the density of the composite plates were determined. To characterize fracture behavior of the matrix material and the all-PET composites, Essential Work of Fracture (EWF) and J-integral methods were adopted. Based on the results one can state that the UD and CP reinforcement could enhance significantly the mechanical properties respect to PETG but in case of fracture toughness only the UD composite passed matrix value and CP composite remained much below.
